Chapter 3—Lossy Capacitors 3–2 usually express the complex permittivity by and tanδ,where tanδ = (3) where tanδ is called either the loss tangent or the dissipation factor DF. The real part of the permittivity is defined as = r o (4) where r is the dielectric constant and o is the permittivity of free space.
